MOVINQ-PICTURE FILM.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed May 7,1906. Serial No. 316,622.

To all whom it may concern: Be it known that we, CHARLES J. BENsINGEnand MoN'rronn R. EULLER, citizens of the United States,

residing at Findlay, in the county of Hancock and State of Ohio, haveinventedcertain new and useful I picture films.

'The object of. the invention is to provide a film of' this characterhaving means whereby the emulsion side of'the film will be protectedfrom becoming marred or scratched, and the edges of the film prevented'from being cracked or torn.

With the above and other objects in view, theinvention consists ofcertain novel features of construction, combination and arrangement ofparts, as .will be hereinafter described and claimed.

In the accompanying drawings:Figure 1 is a plan view of one side orsection of the film constructed in accordance with the invention; Fig. 2is a similar view of the 0 posite side; Fig. 3 is a longitudinalsectional view on the line 33 of Fig. 1; and Fig. 4 is a detailperspective view of a section oithe protecting tape before being appliedto the film.

Referring more particularly to the drawings, 1 denotes the film, whichis provided along each edge with the usual apertures or perforations 2.Adapted to be arranged adjacent to each edge of the'film over theperforations 2 is a narrow, thin, flexible strip or tape project throughthe apertures or perforations 2 in the .tape, and are bent downwardlyinto engagement with the outer or plain side of the film, as shown,thereby securely fastening the strip or tape to the film.

By providing protecting s rips and securing the same to the film asherein shown and described, the emulsion side of the film will beprotected from being scratched or rubbed when the film is being used,said strip also strengthening the film and preventing the edges of thesame from becoming torn or broken. The

cutting of the tongues 4 in the strip or tape as herein shown anddescribed also provides openings 5 in the tape, which 'correspcnd to theopenings 2'in the film and the tongues 4 protect the edges of saidopenings from being torn or worn by continuous use in thernachine.

A protecting strip constructed as herein shown and described may beapplied both to new films purposely constructed to receive them or toold films by forming apertures along the edges thereof to receive theclenching tongues formed on the tape.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiringmore'extended explanation.

Various changes in the form, proportion and the minor details ofconstruction maybe resorted to without departing from the principle orsacrificing any of the advantages of this invention, as defined by theappended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters-Patent, is'.

1. A moving picture film having formed therein adjacent to each edge aseries of holes or perforations, flexible metal tapes adapted to besecured to one side of said film adjacent to each edge of the same andhaving perforations registering with the perforations in the film, andmeans whereby said tapes are firmly secured to the film, substantiallyas described. v

2. A moving picture film having formed therein adjacent to each edge aseries'of perforation s or openings, flexible metal strips arranged. ,onone side of said film over said openings, and fastening tongues formedin said strips to enter the openings in said film, substantially asdescribed.

A moving picture film having formed therein adjacent -to each edge aseries of apertures, flexible metallic strips arranged on one side ofsaidfilm adjacent to each edge and over the apertures of the same,attaching tongues struck or cut in said metallic strips and bentlaterally therefrom to form openings in the strips, said tongues beingadapted to enter the openings in said film and to be clenched againstthe opposite side of the latter, thereby protecting the walls of saidopenings and securing said strips in place, substantially as described.

4 A metallic protecting strip for moving picture films, having formedtherein a series of. holes and integral, angularly bent securing tonguesformed on said strip by the cut ting of said holes, substantially asdescribed.

In testimony whereof we have hereunto set our hand in presence of twosubscribing witnesses.
